1'0 all whom it may concern.- I

Be it known that 1 ANKIN, a citizen of t ding at Louisville CHARLES CALHOUN l he United States, rein the county of Jefferhave invented useful in certain new and Plow-Stocks; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to I make and use the same, reference being had I to the accompanying drawings, and to the t figures of reference marked thereon, which form a part of this specification. l My invention relates to plow stocks and i I l l I l iprovements in l has for its object to provide a device of this kind upon which may be attached various kinds of blades, shovels, sweeps. etc.

A further object of my invention is to provide a plow stock which is constructed entirely of metal and which can be quickly and easily knocked down for convenient ship'- ment, and which can be as readily assembled. A further object of my invention is to proclass which is particularly simple in its construction, cheap and easy to manufacture, strong, durable and i efficient. 4 i

A further object of my invention is to provide a device of this kind wherein the stand become tighter as the strain increases on the standard.

With all these objects in view my invention consists in the novel construction and particularly consists in the novel construci 'tion of the beam; and my invention also con; sists in the combination between the beamgj I arrangement of the parts, and my invention ard may be adjusted to any desired angle, and which has the part so constructed and handles and standard, all of which will be first fully described an ally pointed out in the" appended claims.

Referring to the accompanying drawing: Figure l is a perspective View of a plow d afterward specificstock constructed in accordance with my invention. Fig. 2 is a longitudinal sectional i View the end of the handles and end of the l )eam being broken away.

Like numerals of reference indicate the l same parts throughout the several figures in l which; y 1 indicates the stock which comprises the handles 3, standard 4 and standard brace 5.

[ desired angle the clamp 10 is Referring to Fig. 2 it will the extreme ends the forward flattened ends 7, clevis and the rear end 7 being flattened to form a 45 degree extension, the rear flattened portion being wid of the metallic tubular beam.

As will appear from Fig. l the lower ends 8, of the handles 3 are flattened preferably in a confined die in such manner that the said flattened ends will be original diameter of the tube.

10 indicates the beam clamp which is composed of two sections 11 and 12 which encompass the beam .2, said clamp 10 being slidable on the beam 2 as indicated in dotted lines in Fig. 2. The standard 4 is formed like a loop, the upper ends l3 straddling the lower portion of the beam clamp 10 as clearly shown. and is secured thereon by means of a bolt i l. The handles 3 are secured on the flattened end 7 of the beam 2 by means of suitable bolts or rivets 13, the extreme lower ends of the handles 3 accommodating the standard brace 5 which is secured to the ends of the handles by means of a bolt or rivet 16, which standard brace 5 is pivoted to the standard t by means of a suitable bolt or rivet 1T. Having thus described theseveral parts of my invention its operation is as follows: The beam 2 being constructed preferably from a hollow tube has its ends flattened as before described. The handles which are preferably tubular have their lower ends flattened as shown in Fig. 1 and are secured to the'flattened end of suitable bolts or fastenings 15. The beam clamp 10 is secured on the beam 2 and the standard fastened to the clamp as shown in Fig. 1; the standard brace 5 being then secured in position shown in Fig. l the stock is then ready to receive its blade.

In order to adjust the standard to any loosened so be seen that of the beam 2 are flattened, G forming its er than the diameter no wider than the of the beam by means,

that the same is slidable on the beam 2. Any

movement of the clamp 10 onthe beam 2 obviously alters the angle of the standard 4 as shown in.- dotted lines in F ig'. 3 and by this simple method any desired adjustment can be quickly and readily accomplished.

Q As will or rivet 17 which connects thestandard brace 5 to the standard 4 becomes the fulcrum for the standard 4;.c0nsequent1y all strain applied to the standard 4 acts on the fulcrum appear from the drawing the bolt.

1'? which draws down. on the beam clamp 2, thus hating a tendency to tighten the clamp on the beam L and preventing all sliding or movement of the clamp 10 on the beam 2.

Having thus fully described my invention what i claim as new and desire to secure by Letters Patent of the l nited States, is:

l. A plow stock comprising a tubular metallic beam, handles, standard and standard brace, said beam being flattened at its forward end to form a cleris and flattened at its rear end. the portion at the rear end being wider than the diameter of the tubular beam, the lower ends of said handles being flattened to conform to the flattened end of said beam, a beam clamp for said beam to which beam clamp said standard is pivoted, said standard brace bein; pivoted to the flattened ends of said handles and piv oted t0 the said standard.

metallic beam, handles and a standard, the

-r plow stoek comprising a tubular metallicbeaiu, handles and a standard, the rear end of said beam being flattened to form a' bearing for the handles, the lower ends of said handles being flattened to con f0['111 to the flattened surface of the said beam, said handles straddling the flattened surface of the said beam.

3. A plow stock comprising a tubular rear end of said bean1..bei n;' flattened to receive the handles. the lower ends of the said handles conforming to' the flattened surface of the said beam.

In testimony whereof, I afliX my signa- 3 ture. in presence of two witnesses.
